我有一个新字段要添加到我的数据库中。所以我说
python manage.py makemigrations
这正确地创建了kernel/migrations/0003_auto_20150726_1911.py
。我检查了内容,一切看起来都很好。
I say
python manage.py migrate
我不太高兴。文件kernel/migrations/0002_auto_20150707_1459.py
,这会添加字段date_of_birth
到餐桌userprofile
,失败。尽管我很确定迁移已应用。因此迁移 0003 永远不会被应用。
这就是生产。 :(
我完全不知道该怎么做才能应用 0003 而不是软管 django。建议?
其余部分是支持文档:
